U+29D6 "⧖" White Hourglass Unicode Character
Unicode Version 17.0
⧖
U+29D6 "⧖" White Hourglass is a typographic symbol belonging to the Miscellaneous Mathematical Symbols-B block, and it depicts an hourglass shape with a white or hollow interior, often used in mathematical or technical contexts to represent concepts of time, process intervals, or temporal operations. Its design consists of two triangular halves meeting at a central point, echoing the classic sand timer motif but rendered in outline form to distinguish it from solid or filled symbols. This character may appear in diagrams, logic puzzles, or specialized notation systems, though it is not commonly found in standard text and is primarily supported by fonts that include extensive Unicode coverage.
